One-Pot Transformation of RCHO to (E)-RCH=CHSiMe₃ Using CHI₃, Mn, Me₃SiCl, and a Catalytic Amount of CrCl₂

All articles of this category Iodoform is reduced with manganese in the presence of Me 3 SiCl to give Me 3 SiCHI 2 ( 1 ). A one-pot transformation of aldehydes to ( E )-1-alkenyltrimethylsilanes is then performed with iodoform, manganese, Me 3 SiCl, and a catalytic amount of chromium(II) chloride in THF via in situ formation of 1 . geminal dichromium reagent - geminal diiodo compound - ( E )-1-alkenylsilane - chromium(II) - chromium(III) - manganese
